Oregon Wolfe barley genetic stocks – Research and teaching tools for next generation scientists

Journal of Plant Registrations, Volume 19, Issue 3, September/December 2025.
Abstract The Oregon Wolfe Barley (OWB) mapping population (Reg. no. MP‐4, NSL 554937 MAP) is a resource for genetics research and instruction. The OWBs are a set of doubled haploid barley (Hordeum vulgare L.) lines developed at Oregon State University from the F1 of a cross between Dr. Robert Wolfe's dominant and recessive marker stocks.

Verhuellia is a segregate lineage in Piperaceae: more evidence from flower, fruit and pollen morphology, anatomy and development [PDF]

, 2010
Background and Aims The perianthless Piperales, i.e. Saururaceae and Piperaceae, have simple reduced flowers strikingly different from the other families of the order (e.g. Aristolochiaceae).

Morphological markers for microspore developmental stage in maize

Brazilian Archives of Biology and Technology, 2008
The use of maize in anther culture has been limited because only few genotypes presented a high androgenetic potential. Obtaining the proper stage of microspore development at culture initiation is one of the most crucial factors for success in the ...

The making of gametes in higher plants [PDF]

, 2005
Higher plants have evolved to be one of the predominant life forms on this planet. A great deal of this evolutionary success relies in a very short gametophytic phase which underlies the sexual reproduction cycle. Sexual plant reproduction takes place in

Genome‐wide association study identifies QTL and candidate genes for grain size and weight in a Triticum turgidum collection

The Plant Genome, Volume 18, Issue 1, March 2025.
Abstract Wheat breeders are constantly looking for genes and alleles that increase grain yield. One key strategy is finding new genetic resources in the wild and domesticated gene pools of related species with genes affecting grain size. This study explored a natural population of Triticum turgidum (L.) phenotyped for grain weight and size‐related ...

Temporal sensitivity of rice seed development from spikelet fertility to viable mature seed to extreme-temperature [PDF]

, 2015
Extreme temperature during reproductive development affects rice (Oryza sativa L.) yield and seed quality. A controlled-environment reciprocal-transfer experiment was designed where plants from two japonica cultivars were grown at 28/24 ⁰C and moved to ...

Patterns and Drivers of Pollen Temperature Tolerance

Plant, Cell &Environment, Volume 48, Issue 2, Page 1366-1379, February 2025.
ABSTRACT Pollen, a pivotal stage in the plant reproductive cycle, is highly sensitive to temperature fluctuations, impacting seed quality and quantity. While the importance of understanding pollen temperature limits (Tmin, Topt, Tmax – collectively PTLs) is recognized, a comprehensive synthesis of underlying drivers is lacking.
